GObject-introspection event loop reactor.
Method | __init__ | Undocumented |
Method | registerGApplication | Register a Gio.Application or Gtk.Application ,
whose main loop will be used instead of the default one. |
Instance Variable | _gapplication | A Gio.Application instance that was registered with
registerGApplication . |
Inherited from GlibReactorBase:
Method | input_add | Undocumented |

for monitoring ability to write data. |
Method | getReaders | Retrieve the list of current FileDescriptor
monitored for reading. |

monitored for writing. |
Method | removeAll | Remove monitoring for all registered FileDescriptor s. |
Method | removeReader | Stop monitoring the given FileDescriptor
for reading. |

Method | iterate | One iteration of the event loop, for trial's use. |
Method | crash | Crash the reactor. |

Method | callLater | Schedule a DelayedCall . |
Instance Variable | _sources | A dictionary mapping FileDescriptor
instances to GSource handles. |
Instance Variable | _reads | A set of FileDescriptor

instances currently monitored for writing. |
Instance Variable | _simtag | A GSource handle for the next simulate
call. |
Method | _handleSignals | Extend the basic signal handling logic to also support handling SIGCHLD to know when to try to reap child processes. |
Method | _ioEventCallback | Called by event loop when an I/O event occurs. |
Method | _add | No summary |
Method | _remove | Remove monitoring the given FileDescriptor

Method | listenUDP | Connects a given DatagramProtocol
to the given numeric UDP port. |

Method | listenUNIX | Listen on a UNIX socket. |
Method | listenUNIXDatagram | Connects a given DatagramProtocol
to the given path. |
Method | connectUNIXDatagram | Connects a ConnectedDatagramProtocol
instance to a path. |
Method | adoptStreamPort | Create a new IListeningPort
from an already-initialized socket. |
Method | adoptStreamConnection | |
Method | adoptDatagramPort | Add an existing listening SOCK_DGRAM socket to the reactor to monitor for read and write readiness. |
Method | listenTCP | Connects a given protocol factory to the given numeric TCP/IP port. |
Method | connectTCP | Connect a TCP client. |
Method | connectSSL | Connect a client Protocol to a remote SSL socket. |
Method | listenSSL | Connects a given protocol factory to the given numeric TCP/IP port. The connection is a SSL one, using contexts created by the context factory. |
Instance Variable | _childWaker | None
or a reference to the _SIGCHLDWaker
which is used to properly notice child process termination. |
Method | _uninstallHandler | If a child waker was created and installed, uninstall it now. |
Method | _removeAll | Remove all readers and writers, and list of removed IReadDescriptor s
and IWriteDescriptor s. |
Inherited from _SignalReactorMixin (via GlibReactorBase, PosixReactorBase):
Method | startRunning | Extend the base implementation in order to remember whether signal handlers should be installed later. |
Method | mainLoop | Undocumented |
Instance Variable | _installSignalHandlers | A flag which indicates whether any signal handlers will be installed during
startup. This includes handlers for SIGCHLD to monitor child processes,
and SIGINT, SIGTERM, and SIGBREAK to stop the reactor. (type: bool ) |
Method | _reallyStartRunning | Extend the base implementation by also installing signal handlers, if
self._installSignalHandlers is true. |
Inherited from _DisconnectSelectableMixin (via GlibReactorBase, PosixReactorBase):
Method | _disconnectSelectable | Utility function for disconnecting a selectable. |
Inherited from ReactorBase (via GlibReactorBase, PosixReactorBase):
Instance Variable | running | See IReactorCore.running |
Method | installResolver | See IReactorPluggableResolver . |
Method | installNameResolver | See IReactorPluggableNameResolver . |
Method | nameResolver | Implementation of read-only IReactorPluggableNameResolver.nameResolver . |
Method | wakeUp | Wake up the event loop. |
Method | doIteration | Do one iteration over the readers and writers which have been added. |
Method | resolve | Return a Deferred that will resolve a hostname. |
Method | sigInt | Handle a SIGINT interrupt. |
Method | sigBreak | Handle a SIGBREAK interrupt. |
Method | sigTerm | Handle a SIGTERM interrupt. |
Method | disconnectAll | Disconnect every reader, and writer in the system. |
Method | fireSystemEvent | See twisted.internet.interfaces.IReactorCore.fireSystemEvent. |

Method | startRunning | Method called when reactor starts: do some initialization and fire startup events. |
Method | getDelayedCalls | No summary |
Method | timeout | Determine the longest time the reactor may sleep (waiting on I/O notification, perhaps) before it must wake up to service a time-related event. |
Method | runUntilCurrent | Run all pending timed calls. |

Instance Variable | _stopped | A flag which is true between paired calls to reactor.run and
reactor.stop . This should be replaced with an explicit state
machine. (type: bool ) |
Instance Variable | _justStopped | A flag which is true between the time reactor.stop is called
and the time the shutdown system event is fired. This is used to determine
whether that event should be fired after each iteration through the
mainloop. This should be replaced with an explicit state machine. (type: bool ) |
Instance Variable | _started | A flag which is true from the time reactor.run is called until
the time reactor.run returns. This is used to prevent calls
to reactor.run on a running reactor. This should be replaced
with an explicit state machine. (type: bool ) |
Instance Variable | _registerAsIOThread | A flag controlling whether the reactor will register the thread it is
running in as the I/O thread when it starts. If True ,
registration will be done, otherwise it will not be. |
Instance Variable | _exitSignal | See _ISupportsExitSignalCapturing._exitSignal |
Method | _reallyStartRunning | Method called to transition to the running state. This should happen in the during startup event trigger phase. |

Method | _doReadOrWrite | fd is available for read or write, do the work and raise errors if necessary. |
Register a Gio.Application
or Gtk.Application
,
whose main loop will be used instead of the default one.
We will hold
the application so it doesn't exit on its own.
In versions of python-gi
3.2 and later, we exit the event loop
using the app.quit
method which overrides any holds. Older
versions are not supported.
